Thyme-RL: Think Beyond Images

Thyme-RL, developed by Kwai-Keye, is a 7 billion parameter multimodal model with a 32768-token context length that redefines image understanding by moving beyond traditional "thinking with images" paradigms. It achieves this by autonomously generating and executing diverse image processing and computational operations through executable code. This capability significantly enhances its performance on high-resolution perception and complex reasoning tasks.

Key Capabilities

  • Autonomous Code Execution: Generates and executes image processing and computational code.
  • Enhanced Perception: Excels at high-resolution image perception.
  • Complex Reasoning: Demonstrates strong performance in complex reasoning tasks.
  • Novel Training Strategy: Utilizes a two-stage training approach combining supervised fine-tuning (SFT) with reinforcement learning (RL).
  • GRPO-ATS Algorithm: Leverages the innovative GRPO-ATS algorithm for a sophisticated balance between reasoning exploration and code execution precision.

Good for
